U
Learning About Battery Packs
The computer accommodates up to two rechargeable battery packs
at one time. Battery packs are supported in the:
Battery bay in the computer (primary battery pack)
■
MultiBay in the computer (second battery pack)
■
With the computer turned off, each battery pack will recharge in
less than three hours. With the computer turned on, each battery
pack will recharge in less than five hours.
If two fully charged battery packs are installed, one can be
removed while the computer is on without affecting system
operation. With only one battery pack installed, turn off the
computer or initiate Hibernation before removing a battery, or
connect to external AC power before removing the battery pack.
For more information on using Hibernation, see Chapter 5.
Before removing a battery pack when the computer is in suspend,
ensure that the computer is connected to a fully charged battery
pack or AC power source. For more information on using
Suspend, see Chapter 5.
WARNING:
!
There is a risk of fire and burns if the battery pack is not handled
properly. Do not disassemble, crush, puncture, short external
contacts, or dispose of in fire or water. Do not expose to
temperatures higher than 60qC. Replace only with the Compaq
spare designated for this product.
Your computer contains a lithium-ion battery pack.

Using a New Battery Pack
Charge the battery pack in the computer's battery bay or a
MultiBay while connected to an external power source or while
docked in the optional port replicator.
You can also charge up to two battery packs in the optional
battery charger. However the battery charger has only one slot for
the main battery and one slot for the MultiBay. Therefore, you can
only charge two battery packs at one time if one is the main
battery and the other battery is for the MultiBay.
IMPORTANT:
used for the first time. The battery pack will work without being
fully charged, but the battery gauge will not show an accurate
charge until the battery pack receives its first full charge.
A new battery pack should be fully charged before it is
Charging Battery Packs
Battery packs charge in the following sequence:
1. The primary battery in the computer battery bay
2. A second battery pack in the computer MultiBay
Battery packs are discharged in the reverse order, with the battery
pack in the MultiBay depleted first. See Chapter 2 for bay
locations.
To charge battery packs, follow these steps:
1. With battery packs in the battery bay and/or MultiBay,
connect the power cord to the computer and plug it into an
electrical outlet.
2. Turn on the computer if you want to use it while the battery
packs are charging.
4-2 Using Battery Packs
NOTE:
The battery charge light is the right light on the front edge
of the computer. It turns on (solid) when a battery pack (in the
battery bay or MultiBay) is charging. It turns off when fully
charged. It blinks in a low-battery condition.
When the battery charge light turns off, the battery packs are fully
charged.

If the computer will be unused and unplugged from an external
power source for more than two weeks, remove and store the
battery packs.
Proper storage procedures reduce the self-discharge rate of a
battery pack. Store a battery pack in a cool, dry place within the
following temperature ranges.

Maximizing Battery Pack Life
Battery pack operating time varies depending on the system
components, options, and applications used. Battery operating
time can increase by as much as 50 percent by controlling the
energy used by the computer and the energy stored in the battery
pack.
NOTE:
T
he display, processor, and drive components use the
majority of battery power.
To maximize battery pack life, use the following guidelines:
Select the High level of power management (not available
■
under Windows 98). See Chapter 5 for more information on
power management.
Initiate Suspend or Hibernation or turn the computer off when
■
you are not using it.
Reduce the display brightness and select a shorter screen save
■
timeout.
Keep a battery pack in the computer when you are using the
■
computer with external power.
Using Battery Packs 4-5
Disconnect external equipment that does not have its own
■
power source. (External equipment connected to the computer
drains the battery pack.)
Exit modem programs when you are not using them.
■
Remove a PC Card when you are not using it.
■
When storing the computer for more than two weeks, remove
■
battery packs and store them separately to reduce the discharge
rate and increase battery life.
Store the battery pack in a cool, dry place when it is not in use.
■
High temperatures cause a battery pack to lose its charge more
quickly and reduce battery pack life. For more information on
storing battery packs, see "Storing a Battery Pack" in this
chapter.
Format diskettes while using external power when possible.
■
(Formatting diskettes increases the drain on a battery pack.)
Recycling Used Battery Packs
To find out if the battery pack recycling program is available in
your area, check the worldwide telephone numbers. If a number
for recycling is not listed for your area, contact your Compaq
authorized dealer, reseller, or service provider.

Managing Power 5-1
Using Suspend (Standby) and Hibernation
You will use the power switch 1, Suspend button 2,
Fn
key 3,
and the power/suspend light 4 as you turn the computer on or off
or place it in Suspend (Standby) or Hibernation.
■
Suspend, called Standby in Windows 98, is an energy-saving
feature that reduces power to system components that are not
being used. When the computer is in Suspend (Standby), your
work is saved in random access memory (RAM) and the
screen is cleared.
■
Hibernation is an energy-saving feature that saves all
information in RAM to a hibernation file on the hard drive,
then shuts down the computer.
If you are leaving your work, consider:
If you plan to resume shortly—Initiating Suspend (Standby)
clears the screen, uses less power than leaving the computer on,
and your work returns instantly to the screen when you press the
suspend button. A fully charged battery pack can support Suspend
(Standby) for up to a week, unless frequent charging and
discharging has shortened battery pack life.
5-2 Managing Power
If the computer will be disconnected from external power for
more than two weeks
—To extend the useful life of the battery
pack, shut down the computer, then remove the battery pack and
store it in a cool, dry place.
If you plan to resume within two weeks
—Initiating Hibernation
clears the screen, saves your work to the hard drive, and uses less
power than Suspend (Standby). Returning to work saved in
Hibernation takes a little longer than returning to work placed in
Suspend (Standby), but is much faster than returning to your place
manually after restarting the computer. A fully charged battery
pack supports Hibernation indefinitely.

CAUTION:
or to prevent loss of information, observe the following precautions.
Back up the information on a hard drive before removing it.
■
To reduce the risk of personal injury from hot surfaces,
To prevent damage to the computer or removable drive
Failure to back up the hard drive can result in loss of
information if the drive is handled improperly.
If there is a diskette, compact disc, or digital video disc in a
■
drive, remove it prior to removing the media from the
computer.
Do not remove a CD-ROM or DVD-ROM drive with the tray
■
extended. Before removing the drive, push the drive tray into
the drive.
Ensure that you are discharged of static electricity before
■
handling a removable drive. Electrostatic discharge can
damage electronic components. When handling a removable
drive, always grasp the outer case and avoid touching the
connectors.

■
force may damage the connectors.
Carefully handle the removable drive. DO NOT DROP IT.
■
Avoid exposing a hard drive to products with magnetic fields
■
such as video and audio tape erasure products, monitors, and
speakers.
Do not spray the drive with cleaners or expose it to liquids.
■
Avoid exposing the drive to temperature extremes.

Changing the Startup Sequence with MultiBoot
If more than one drive is in the system, the computer selects the
drive to start from by searching for (1) a bootable CD-ROM or
DVD-ROM; (2) a bootable diskette; and (3) a bootable hard drive.
The computer can start from:
Any bootable hard drive in the computer or diskette drive.
■
Any bootable diskette or hard drive in an optional docking
■
base.
Any bootable CD-ROM or DVD-ROM.

Travel Connection Checklist
If you experience connection problems while using the modem
outside your home country, the following suggestions may help.
■
Check the telephone line type—the modem requires an
analog, not a digital, telephone line. A telephone line
described as a data line, fax machine line, modem line, or
standard telephone line, is probably an analog line.
■
Check for pulse or tone dialing—Dial a few digits on the
telephone and listen for clicks (pulses) or tones. Then set your
communication software to the corresponding dialing mode
(pulse or tone).
■
Check the telephone number you are dialing and the
response of the remote modem—Dial the telephone number
on the telephone, wait for the remote modem to answer, then
hang up.
